To aZZ whom it may concern:

. Be it known that I, DAVID S. WILLIAMS, a citizen of the United- States, residing at Philadelphia, in the county "of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Making Pies, of which the following is a specification.

My invention embodies a machine for making pies in a manner that will not tend to toughen the dough and in which the finished product will be cheaper, more uniform in quality, and shorter in texture, and consequently better, than the product made by the rolling process.

In carrying out my invention I employ an endless conveyor made up of a number of sections provided with openings to receive the plates. The plates or pans are automatically fed to the conveyor, and each as it passes along is provided with a thick lump or cake of dough, which is brought under the action of a heated plunger and is pressed into the shape desired to be given to the lowercrust. The crust thus formed is then carried to the filling mechan ism,where the requisite amount of fruit or meat is evenly distributedover its surface. Following this operation and prior to the forming of the upper sheet of crust the outer edge of the lower crust is moistened to cause'the upper'crust to adhere to it,'and by themechanism next'employed the top crust I is pressed into shape, perforated, and pressed upon the lower crust, after which the irregular edges are trimmed off, the top sized, and the product is ready for baking.

The nature of my improvements will he more clearly understood by reference to the accompanying page of drawings, in which Figure 1 illustrates a plan view of a machine constructed in accordance with my invention. Fig. 2 represents a side elevation of the same. Fig. 3 is a detached perspective view of a portion of the plate-feeding mechanism, showing more clearly the manner in which the plates are released. Fig. 4 denotes a sectional plan of the plate-feeding mechanism, taken on a line 4 4 of Fig. 3. Fig. 5 represents a vertical sectiontaken on a line 5 5 of Fig. 4.. Fig. 6 is a similar view modified to show the manner inwhich slidable plates may beemployed in place of the ring form shown in Figs. 3, 4, and 5. Fig. 7 indicates a vertical section of the lower-'crust-forming mechanism, taken on a line 7 7 of Fig. 2. Fig. 8 shows a vertical section of the filling mechanism, taken on a line 8 8 of Fig. 2. Fig. 9 denotesa vertical section of the moistening mechanism, taken on a line 9 9 of Fig. 2. Fig. 10 illustrates a vertical section of the top-crust-forming mechanism, taken on a line 10 10 of Fig. 2; and Fig. 11 represents asimilar vertical section of the trimming mechanism, taken on a line'll ll of Fig. 2.

Referring in general to the reference-letters of the drawings, A denotes the frame of the machine; B, the inain driving-shaft; O, the endless conveyor; D, the plate-feeding mechanism; E,thelower-crust-forming mechanism; F, the filler mechanism; G, the moistening mechanism; H, the upper-crust-forming mechanism; 1, the trimming mechanism, and J the mechanism for sizing the top crust.

Considering the parts in detail, the main drivingshaft B is provided, respectively,

with fast and loose driving-pulleys Band B and with a small gear wheel or pinion B which meshes with gear-wheels B and B,

mounted, respectively, on shafts B and B The endless conveyor C is made up of a nu mber of links 0', which are hinged together and have at this point rollers 0*, which rest upon rails C and C during the greater part of their travel and are carried at each end of the machine by sprocket-wheels C and 0 mounted upon shafts G and C The shaft 0 by which the conveyor 0 is driven, is provided with a stanwheel C operated by a corresponding ratchet member O mounted upon the shaft B The lin ks or. sections 0' of the conveyer are each provided with an opening 0 cutout in such a manner as to closely embrace and form an outer wall for the plates to be deposited therein, as well as to form a ledge to engage the top flange of the plate.

The plate-feeding mechanism D comprises a frame A, upon which is fastened a baseplate D, from which project guides or uprights D between which the plates d are supported. Each guide is provided with an escapement-rin g D which has two mutilated rings D and D arranged in such a manner that the upper ring will engage the rim of the plate adjacent to the one at the bottom before the lower ring releases its hold upon 5 the lower plate and it is allowed to drop to the conveyer O.

The rings 1) have united to them bell-crank levers D which are joined together by connecting-rods D the last bell-crank lever of :o the series being connected by a link D to a lever D which is operated in one direction by a cam D on the shaft 0 and in the other direction by a spring S.

The conveyer C after receiving a plate is I carried forward one step, and the plate is then supplied with a thick cake of dough of considerably less diameter than the crust it is to form. In practice I prefer to feed the plates from the belt of a single-stamp cakecutting machine; but as this does not form any part of my present invention I will proceed to describe the operation as it would be carried out after manually placing a cake of dough into the plate. As the conveyer is again moved forward in the direction of the arrow the dough is brought under the action of the lower-crustforming mechanism E. This machine comprises supporting-frames A between which is firmly supported abodplate E, arranged in line with the bottom of the plate d, and a cross-head ,E, carrying a plunger E which latter is of the same contour as the plate. The crosshead E is guided in the upper part of the frame A and is operated by connecting-rods E studded to cranks E which are firmly mounted upon a shaft E One of the cranks E, as shown in Fig. 2, is in the form of a bell-crank and has a long arm E to which is fulcrumed a long rod E", which receives motion from a crank E mounted upon theshaft B The method of pressing the dough into the plate cl to form the lower crust as distinguished from the method of rolling out a sheet of dough and then placing it upon the plate has distinct advantages, for aside from being a quicker operation it has the ad vantage of producing a shorter crust, or, in other words, a crust which is when baked exceedingly light and go tender. In the course of my experiments this method was at first attended with difiiculties, the chief of which was the tendency of the pie-dough, which is very sticky, to ad-.

means a portion of the lard contained in the dough is melted,which,spreading over the surface of the plunger, acts to prevent the dough The next operation is perfrom sticking.

the character of the goods.

formed by the filling mechanism F, which comprises a receptacle or tank F, mounted upon standards A A and provided with a conveyer F consisting of a chain F", passing over sprocket wheels F and F and carrying a number of small buckets F which deliver the contents of the receptacle to a chute F The conveyer is driven from the shaft F by a sprocket-wheel F which is provided with a sprocket-chain F receiving its motion from a sprocket-wheel F mounted on the shaft B The plate 61 upon reaching this point of the operation is slightly raised by riding over a turn-table F which releases the plate from engagement with the conveyor 0 and enables it to be turned through the medium of the shaft F having a pulley F driven by a belt F carried by a pulley F", mounted upon the shaft B The mouth of the chutef is located at one side of the center of the plate containing the lower crust, so that as it is turned by the turn-table F the fruit or other material fed to it will be evenly distributed. In some grades of pics, as is well known, a top crust is omitted, and in making this class of work all of the following operations except the trimming mechanism may be temporarily thrown out of action.

Before applying the top crust to the edge of the lower crust I prefer, although it is not in all cases necessary, to moisten by a mechanism G the rim of the lower crust, which is accomplished by brushes G G, mounted upon an arm G which is carried by a vertical shaft G journaled in a frame G and driven by a pulley G The brushes G are moistened by tubes g g, leading therefrom to a pan G into which water or other moistening fluids may be slowly caused to drop, or, as shown, it may be provided with a sponge or other porous medium, from which the water may be slowly fed to the tubes.

The uppercrust-forming mechanism H comprises upright frames A in which is guided a cross-head H, upon which a cake of dough intended to form the upper crust may be placed. This cross-head is caused to move up and down by means of connecting-rods H which are pivoted to the cross-head and receive their motion from cranks H secured to the shaft-B After receiving the dough the cranks and arms associated therewith carry the cross-head upward,where the dough is brought in contact with a plate H and pressed to the thickness desired to form the crust. The plate H is provided with a gasburner H5, similar to that employed in connection with the lower-crust-forming mechanism E, with the object of preventing the dough from adhering to the plate H The plate H is also provided with small pins h, which serve to perforate the crust or to otherwise mark it for the purpose of designating The cross-head H on its downward movement is caused to turn a half-revolution by means of a-rack 1-1.

operating a pinion H which is fastened toone of the trunnions H of the cross-head, so that a further downward movement of the cranks will cause the crust to be delivered to the plate containing the lower crust, which having been previously moistened around the upper edge will cause the upper crust to adhere to it and permit the cross-head to rise,

leaving the sheet of dough in contact with the lower crust. The rack H which causes the cross-head to turn, is connected to and operated by a lever H supported upon a shaft 'H and operated by a cam H engaging the cam-roller H. The next operation is that of trimming or cutting away the irregular edges of the crusts which project outside of the piewhich supports the cutters, is lifted out of the path of the crusts during the time the conveyer O is in motion by a roller I, hearing upon the face of the conveyer-belt. This roller is connected to an arm I", mounted on a shaft 1 which carries another arm 1 yoked to the shaft 1 When, however, the belt 0 has moved forward and again stopped, the cutters are brought into action to trim the crust by the roller 1 dropping into adepression 1 one of which is located on a line.

central with the plate in eachsection of the conveyer, and as the roller 1 falls the cutters I are brought into a position to perform the flowing too rapidly to the brush by means ofv sponges or other absorbents placed in the res-: ervoir J or, if desired, the fluid may be fed to the reservoir by a small pipe and regulated by a valve in any well-known way to limit the quantity delivered in a given time. The brush J and reservoir .1 are mounted upon a shaft J which is supported in a frame J and motion is given to the shaft and parts carried by it by a bevel-gear J meshing with a bevel-pinion J on a shaft J ,which shaft is driven by a sprocket-wheel J 8 through the medium of a sprocket-chain J and another sprocket-wheel J mounted upon the shaft B. The driving-shafts of both the mechanisms G and I receive their power through the mechanism J, which has a pulley J mounted upon its driving-shaft J 3 and which carries a belt running from it to a pulley 1 driving the trimming mechanism. On the shaft I is another pulley 3' which conveys pulley G7 on the shaft G It will be seen from the nature of my invention' that I do not limit myself specifically to the mechanism by which the several operations of my machine are carried out, except in such of the claims as it has been thought advisable or necessary to point out such specific mechanism, and it is obvious that many mechanical equivalents other than those shown may be adapted without departing from the spirit of my invention.
